MATTRESS.

SPECIFICATION forming part of Letters Patent No. 620,591, dated March '7, 1899. Application filed August 18, 1898. Serial No. 688,908. (No model.)

To all whom, it may concern:

Be it known that 1, WILLIAM E. JACKSON, J r., a citizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented certain new and useful Improvements in Mattresses, of which the following is a specification, reference being had therein to the accompanying drawings.

The objects of my improvement are to provide a light but strong and inexpensive mattress particularly suitable for use during the summer months or in warm climates and having sanitary advantages. I attain these obj ects by the construction illustrated in the accompanying drawings, in which- Figure l is a perspective view of the mattress complete constructed in accordance with my invention. Fig. 2 is a perspective view of the inner frame thereof. Fig. 3 is a plan of the canvas of the mattress. Fig. 4 is a vertical section of a portion of the mattress on a larger scale. Fig. 5 is a perspective view of one of the corners of the outer frame broken away partly. Figs. 6 and 7 represent in perspective modified forms of pieces of the pipe frame with canvas clamped thereby.

In said drawings, A represents a rectangular double frame or a pair of frames made of light tubing, which may be left unwelded lengthwise and consisting of a rectangular base-frame a, a similar rectangular top frame a of the same size, and uprights a at each corner, having double angular elbows a and permanently uniting the frames a and a Said double frame may be made of any desired size to fit into any regular iron or wooden bed having the ordinary width of three, three and a half, four, and four and a half feet, and its height is generally eight inches; but said height and width may be of any desired size. To produce the mattress, another single rectangular frame B is used. It consists of four lengths of light tubing, two pieces I) being of equal length for the sides of the frame and two pieces 19 for the ends of said frame. Elbow-pieces b are used to receive the ends of thepiecesband b Their outer angle is preferably rounded to partly prevent the bruising of furniture against which it may come in contact. To permanently connect the pieces length of the frame A, but each side and end has a flap c to be coiled around the pipes b b of said frame, or, in other words, the outer edge of each flap is either clamped into a slot, as shown in Fig. 6 or Fig. 7, or is cemented to one of said pipes b or 6 and said pipe is rolled tightly in said flap until Within an inch of the body proper of the canvas. The ends of said pipe are then made to receive a portion of the elbows or are inserted into the elbows b and said partsdrilled and riveted together. The operation is repeated for each flap of the canvas to secure it coiled upon its pipe, and said canvas is thereby somewhat tightly stretched to the frame B. In the modification shown in Fig. 6 the pipe b is left incomplete in its manufacture, the welding of its edges being omitted and its cost thus reduced. Its longitudinal slit b is used to receive the doubled-over end of the flap c of the canvas, and in the loop produced by said doubling a piece of cord 5 of the same length as the pipe is inserted to prevent-the withdrawal of said doubled end while the canvas is coiled around the pipe. In the modification shown in Fig. 7 the pipe 1) consists of two troughlike lengths, between which the end of the flap c of the canvas is clamped before said flap is coiled around a pair of said troughlike lengths; but to have the canvas 0 tightly stretched and maintained in said condition spondingly screw-threaded.

upon the flaps c of the canvas. Each one of said turnbuckles consists of two short rods d having their outer ends bent in the form of a hook and their inner ends provided with right-hand and left-hand screw-threads, and an open-eye buckle d, having its ends corre- The upper hook is made to bear upon the flaps c, coiled around the frame B, while the lower hook is in engagement with the bottom of the base-frame Ct. Two or three turnbuckles are made to engage with each long side of the frame and a smaller number are used to engage with the ends of said frame.

Although it is preferred to have the uprights a of the inner frame of the same height at both ends, those intended for the head of the mattress may be-made longer than those for the opposite end, if desired, to render the canvas surface slightly inclined.

The canvas or cover may be white or striped, as may be desired, and it can be maintained under such tension that there will be hardly any sagging under the weight of one or more persons lying thereon.

Having now fully described my invention,

I claim- 1. A mattress consisting of a pair of rectangular frames permanently united together, one above the other, uprights connecting them, a rectangular frame loosely surrounding the upper frame of said pair, a canvas sheet or sheet of other material, having flaps secured to the surrounding frame, and ad- 3' ustable tighteners having one end secured to said surrounding frame and the other end to the lower frame of the rectangular pair, substantially as described.

2. In a mattress, the combination of a pair of rectangular frames permanently united together, one above the other, uprights connecting them, a rectangular frame of a size to loosely surround the upper frame of said pair, a textile sheet having flaps secured to the surrounding frame, and adjustable turnbuckles having at one end a hook bearing upon the sheet-flaps secured to the surrounding frame and at the other end a hook in engagement with the lower frame of the rectangular pair, substantially as described.

3. In a mattress the combination of a pair of rectangular frames permanently united together one above the other, uprights connecting them, a rectangular frame of larger size consisting of tubes, and elbow-pieces connecting the ends of said tubes, rivets uniting said elbow-pieces and tubes, a sheet having flaps, and each flap coiled around and secured to one of the tubes of the outer frame, and adj ustable turnbuckles uniting said outer frame with the lower frame, of the rectangular pair, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
